Thus, to the extent that a young adult with mild mental retardation has selected skills that are well developed relative to others, it may not be accurate to describe those skills in developmental terms. Table 4-4 presents examples of questions that can guide examiners in eliciting information regarding the three social-cognitive processes reviewed here. A strength of this scale is that teachers are asked to record when they estimate behaviors, so the resulting threat to reliability and validity can be appraised. In particular, criticism has focused on the inadequacy of existing techniques for measuring the social domain of adaptive behavior (MacMillan et al., in press). They have provided valuable information that has informed decision making about interventions to improve the social functioning of individuals with mental retardation. Referring to the dual purpose of adaptive behavior scales, Spreat (1999) concluded that it is unrealistic to think that the same test can be used for program evaluation, diagnosis, classification, and individual programming (p. 106). PDF. It is important to note that the Division 33 definition places equal importance on the constructs intellectual functioning and adaptive behavior. No one instrument produced a factor structure that included all of the domains that were identified by the American Association on Mental Retardation (1992). About three-quarters of children with mild mental retardation had two or more domain scores falling in the marked limitation range, compared with slightly less than one-third of the children without mental retardation (last row). The Vineland-3 is a standardized measure of adaptive behavior--the things that people do to function in their everyday lives. 8 Special Education Assessments Find out about what tests are used to diagnose or help students with special needs. Here we review data from the only adaptive behavior test manual that could provide some guidance about the use of cutoff points for adaptive behavior assessment. Several important conclusions are suggested by this comparison, although the specifics might differ if another adaptive behavior scale with a somewhat different structure were used: One-half of children with mild mental retardation (column 2) had a summary score falling in the marked limitation range ( 2 SDs), compared with about 14 percent of children without mental retardation (column 3). Click on an item in the set below to see more info. However, Smith (1989) notes that, at the low end of the normal intelligence norms, a few raw score points can dramatically change the adaptive behavior quotient, and suggests that the norms on students with mental retardation are more useful. Answers to this question have been mixed. . That is, current science suggests that there are various domains of behavior that form the construct of adaptive behavior. For most people, the use of currently available adaptive behavior instruments along with other information on adaptive functioning will improve decisions about mental retardation classification. The person is then asked, What will happen after the protagonist carries out this strategy? Our review of the practice literature reveals that adaptive behavior scales are in wide use by some groups of clinicians. It contains broad domains similar to those found on adaptive behavior scales, which include: personal-social, adaptive, motor, communication, and cognitive. Diagnostic decisions about mental retardation nearly always involve normative comparisons using various derived scores. This information may otherwise be lacking because of inadequacies in existing adaptive behavior measures. The definition also includes the notion that adaptive skills are affected by the presence of appropriate supports and with appropriate supports over a sustained period, the life functioning of the person with mental retardation will generally improve.. Beltran's Behavior Basics. However, children who do meet intellectual and functional criteria for mental retardation also are classified as having disabilities other than mental retardation in some schools and in some cases, and not necessarily consistently so (McCullough & Rutenberg, 1988). The number of activities that are restricted does not represent a marked limitation in activities of daily living, but rather the overall degree of restriction or combination of restrictions must be judged. Research studies in the past decade that employ adaptive behavior measures have used them as outcome measures or to study the structure or dimensions of adaptive behavior, rather than behavioral development. Also, English language norms may be lower than the typical performance of a same-age child in another culture. Adaptive behavior measures are useful in the identification of limitations concurrent with an IQ significantly below average. The SIB-R manual addresses many of the issues that make the scoring interpretation of adaptive behavior scores challenging, including physical disability, the use of adaptive equipment, alternative communication methods, tasks no longer age appropriate, partial performance of multipart tasks, lack of opportunity due to environment or safety, and cognitive ability to understand social expectations for performing behaviors. Both structured and semistructured interviews, when performed by well-trained and experienced clinicians, appear to be the best available safeguard against threats to the reliability and the validity of adaptive behavior assessment. It can be a habit picked up at an early age or can be a behavior that starts after a major life change, illness, or traumatic event. Adaptive behavior assessment information can provide information needed to determine an individual's eligibility for special education services. These other bits of data could include a review of developmental and social history, direct observation of the individual's behavior, verbal reports from interviews, and the use of the other structured and semistructured interviews. The quality of performance may be somewhat more subjective, but a key feature is the appropriateness of a given level of adaptive behavior performance. The skills needed to make a call today are very different from the skills that were required 20 years ago. Areas assessed, and information that may be revealed, include areas of communication, daily living skills, community functioning, socialization, self-reliance skills, and motor skills. 2. Although it is linked to AAMR by name, the ABS does not provide subscale scores in the 10 adaptive skill areas listed in the 1992 AAMR definition of mental retardation. Since other norms should be used for determining a diagnosis of mental retardation, according to the manual, this should not be a problem in the current SSA context. The subscales are similar to general adaptive behavior scales, but there is a greater emphasis on skills required to function in community settings than on basic adaptive skills. Alternative measures to complement intelligence measures began to appear as early as 1916. However, depending on the age range of adult participants without disabilities sampled during norming studies, the ceiling (i.e., the highest level of behavioral performance assessed) may differ across scales and may affect the characterization of the degree of delay manifested. Her true score is likely to fall within the range of 68-76 at a 95% level of confidence. The ABI has a normative sample representative of all school-age children, including those with disabilities, and of a sample with mental retardation. Thus, characteristics of the factor structure of a measure of adaptive behavior have important implications for diagnosis. The SIB provides norms from infancy to adulthood (40+ years), contains 14 adaptive behavior subscales that fall into four major clusters, and provides an additional full-scale broad independence score. Adaptive behavior is behavior that is positive and functional to the individual. Assessments are used for many different purposes in the K12 educational setting. In this section, we discuss a variety of psychometric features of adaptive behavior scales that have implications for decision making about mental retardation. In the characterization of mild mental retardation, the ICD-10 guide points out that, some degree of mild mental retardation may not represent a problem. It goes on to state that the consequences will only be apparent if there is also a noticeable emotional and social immaturity. This statement implies that for individuals with mild mental retardation, intellectual deficits are apparent only when represented by problems in adaptive behavior (emotional and social immaturity). This table is a useful means to summarize and illustrate the detailed description of adaptive functioning that meets listing criteria, which are required to establish eligibility for SSI and DI. This chapter contains material drawn from an unpublished paper commissioned by the committee from Sharon Borthwick-Duffy, Ph.D., University of California, Riverside. Greenspan and Driscoll (1997) proposed a dual nature of competence. They suggest that intelligence, as measured by IQ, is typically viewed as an independent variable that predicts outcomes, whereas personal competence is the combination of what individuals bring to various goals and challenges as well as their relative degree of success in meeting those goals and challenges (p. 130). Generally, these instruments do not have well-established norms but rather have been assessed for their sensitivity with diagnosed cases (e.g., Reiss & Valenti-Hein, 1994), and some scales are more suitable for youth than for children: the Assessment of Dual Diagnosis (Matson & Bamburg, 1998); the Psychopathology Instrument for Mentally Retarded Adults (Balboni et al., 2000; Linaker, 1991; Sturmey & Ley, 1990; Watson et al., 1988); and the Reiss Screen for Maladaptive Behavior (Havercamp & Reiss, 1997; Prout, 1993; Sturmey & Bertman, 1994) For practitioners skilled in clinical interviewing, a field-tested adaptation of a structured clinical interview is available. However, depending on the nature of these provisions, they may reduce the comparability of measures of the related skills from different adaptive behavior scales. For older adolescents, ages 18 to 21, the difficulty level of items often permits identification of either delayed or typical skills. Instead, they differentiate individuals with mental retardation based on the supports they need. Thus, social-cognitive assessment increases the likelihood of making accurate diagnostic and disability determination decisions by increasing the pool of information available to an examiner regarding an individual's functional limitations, while simultaneously reducing the risk of false positive decisions.
